SEATTLE/NEW YORK—Among individuals not receiving antiretroviral treatment, men had twice the level of HIV virus in their blood as women at the same stage in the disease, according to one of the major findings of a three-country Doctors Without Borders/Médecins Sans Frontières (MSF) population survey presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle Wednesday.

Initial results of a clinical trial of the experimental drug favipiravir suggest that it can reduce mortality among patients with low levels of the Ebola virus in their blood, but is ineffective for patients with high viral loads who are very sick with the disease.

MSF urges all parties to the Syrian conflict to facilitate the evacuation of people wounded in recent fierce clashes in the city of Aleppo, where the population has been trapped by fighting and aerial bombardments for months.

BRUSSELS/NEW YORK—A trial of the experimental Ebola drug brincidofovir in Liberia has officially ended due to a significant drop in the number of new Ebola cases and the drug manufacturer’s decision to withdraw from the trial, the international medical humanitarian organization Doctors Without Borders/Médecins Sans Frontières said Tuesday.

NEW YORK—As negotiators hold closed-door meetings in Manhattan this week over a secretive trade deal that could affect the health of half a billion people, the international medical humanitarian organization Doctors Without Borders/Médecins Sans Frontières (MSF) took its protest against the Trans-Pacific Partnership (TPP) to the skies Wednesday, flying an aerial banner that read “Doctors to Obama: Keep #TPP Away From Our Medicines” along the Hudson River.
